moronrnnrvnu CLIPPER.

To all whom it may concern Be it known that we, REX PAoKwooD, ER-

;WIN J. RUST, and EUGENE HAZELE'I'TE, citizens of'the United States, residing at Cleveland, in the county-of Cuyahoga and State of Ohio, have invented new and useful Im: provements in Motor-Driven Clippers, of which the following is a specification.

This invention is a motor driven clipper that may be used upon human beings as well as animals with equally good results in the trimming of hair or fur. 1

One object of this invention is to provide a clipper with an electric motor wherein the construction is simple, strong, and durable. j

Broadly stated, the invention comprises an electric motor having a suitable control therefor, the shaft of the motor being provided at one end with a worm, a frame adapted to be secured to one of the end frames of the motor so that the shaft and worm project .therethrough, a housing for said frame, a shaft upon which is mounted a gear to mesh with the worm, a cam on said I gear, a pivotally mounted lever, one end of which is provided with a yoke to cooperate with the cam, the other end being provided with a connecting end so that it may be OP- eratively connected with the cutting blades or cutting comb, comb teeth positioned adjacent the cutter blades and secured to the frame, the work meshing with the gear and imparting a rotary motion to the eccentric so that the lever and its yoke may produce a reciprocating. and rectilinear motion of the cutting blades relative to the comb blades which are stationary.

One practical form will be described and illustrated in the accompanying drawing, in which view.

Fig. 2 is a plan view of the cam, lever, and gear showing the connection.

In the preferred embodiment shown, an electric motor 6 is providedthat is suitably inclosed by the end frames 7 and 8.

Suitable controlling means may be positioned in the end frame 8, as indicated by the button 9. The end frame 8 may be provided with a flange 10 and through this I flange 10 and end frame '8 projects the armature shaft 11, which carries at its outer end the worm 12. -To cooperate with the flange 10 is a frame 13 which is provided Specification of Letters Patent.

Figure 1 is in part a vertical sectional with a suitable groove 14. This groove 14 may be of suchwidth and depth as to adapt it to cooperate with the flange 10 so tlg at when the frame 13 is connected to the flange 10- it may be securely held as by the set screw 15. 1

v Preferably positioned upon the frame is another flange indicated at 16, that is adapted to pooperate with the housing or cap 17. As shown, the housing 17 is provided with an inturned flange 18 at one end. A groove is formed between the flange 16, and the frame. 13 which forms a seat for the flange 18 of thehousing 17.

The other end of the housing 17 cooper ates with the cutting comb 19 and is adapted to be placed in close proximity thereto to limit the vertical movement of the cutting comb. The housing 17 may be secured to the frame 13 in any usual manner, and they are shown as being connected together by means of a bolt having a head 20, a threaded stem 21, and a sleeve or bearing portion 22.

The threaded stem 21 projects upwardly through asuitable aperture formed in .the housing 17, and to hold the screw in position a nut 23 is employed. When the nut 23 is in operative position, the head 20 bears against-and is seated within a suitable recess 24 formed in the bottom or lower side of the frame 13, and the pressure exerted by thisnut 23 holds the housing 17 and the frame 13 in a predetermined position. It may. also serve to produce tension by a frictional engagement of the outer end oft-he housing where it contacts with the'cutting Patented Oct. 8, 1918..

Application filed August 1, 1917. Serial No. 183,917.

in Fig. 1. As illustrated, it comprises a base 25 and an upstanding portion 26 which has an aperture forming the bearing for the shaft 27. The base 25 is secured to the frame 13 in a suitable manner as shown by the screw 28.

The shaft 27 has mounted thereon a gear 3 formed with engaging portions shown by the fingers 33 and 34. This lever is pivotally mounted upon the bearing portion 22 of the bolt, and has extending from the body 34? of the lever, an arm 35 which terminates in a sector end 36. The cutting comb is provided with a solid or body portion 37 that is connected to the lever through the sector 36 which operates in a suitable" recess 38 formedin said body portion.

As shown, the lever 34: has its projecting arms extending in different horizontal planes to cooperate with the cams and with the body 37 of thecutting comb 19.

To cooperate with the cutting comb 19, the comb teeth 39 are provided. The comb teeth are carried upon a frame indicated at 40, which is provided with a suitable hole through which passes certain holding means,

' one of which is'indicated by the screw 41,

which lies that holds it in engagement with the frame 13.

As shown the frame 41 is stationary and also forms an additional seat which tends to hold the head 20 of the bolt holding the frame 13 and the housing togetherinto firm engagementwith the seat ofv the flange in the underside of'the frame 13. The frame is provided with a shallow groove 40 back of the teeth 39 of the. comb portion. This groove serves to permit the cutting comb 19 to have two supports, one u on the frame 40, and the other in contact with the'comb teeth 39.

As shown, the cutting comb 19 in its reciprocation has one edge and side abutting against the frames 13 and 40. .As shown more particularly "in Fig.1, the frames 13 and 40 provide a shouldered portion to form this bearing at their juncture.

extending beyond the same,

Minor changes in the form, proportions, and details of construction may be resorted to without departing from the spirit of the invention or the 'scope of the appended claim.

What is claimed as new is A device of the class described comprising a hollow handle having a flange at one end, a motor in said handle having a shaft a frame having a recess for receiving the flange, means for removably securing the flange in said recess,

a screw threaded bolt having its lower end carried by the bottom of the frame and extending upwardly, the upper end of said bolt and provided with a flange, said frame having a recess to receive said flange, a nut adjustably securing the housing. in place on the bolt, a plate removably secured to the bottom of the frame and covering the bottom of the bolt, comb teeth formed on the outer end of said plate, said plate having a recess therein ad acent the base of the teeth, a movable cutting comb cooperating with the cutting teeth and provided with a projecting portion engaging said recess, a lever connected with said cutting comb and having a part engaging with said'bolt, and cam means operated by the shaft of the motor and engaging with a part of the lever for operat ng the same.

In testimony whereof we afiix our signatures.
